Question:
Find the distance covered by a moving object in 28 hours if it covers a distance of 72 km in 18 hours.
Correct Answer
112 km
Solution And Explanation
Solution
Given,
Distance = 72 km
Time = 18 hour
Thus, distance covers in 28 hour = ?
Here the speed and time are given. So, we need to find the speed to calculate the distance covers in the given time.
Method (1) Using Formula
Calculation of Speed using formula
Formula to find the speed
Speed = Distance/Time
= 72/18 = 4 km/h
Thus, speed = 4 km/h
Calculation of the distance in the given time using formula
Formula to find the distance
Distance = Speed × Time
= 4 km/h × 28 hour = 112 km
Thus, the distance covered in the given time = 112 km Answer
Method (2) Using Unitary Method
Calculation of the Distance using formula
Given,
Distance = 72 km
Time = 18 hour
Thus, distance covers in 28 hour = ?
∵ In 18 hours the distance covered = 72 km
∴ In 1 hour the distance covered = 72/18 km
∴ In 28 hours the distance covered
= 72/18 × 28 km
= 72 × 28/18 km
= 2016/18 = 112 km
Thus, the distance covered in the given time = 112 km Answer
